vih/woo CARBURETEE.,

and l. do declare the 'following to be a iull,

clear, and exact description oi the invention, such as will enableothers skilled in the art to which it appertains to maire and use thesaine.

My invention relates to improvements in carbureters and moreparticularly to those which areintended for mixing steam. mixed. withair with the mixture oi fuel and air drawn from tbe device by thesuction caused by the engine pistons. I am aware that numerous types ofcarbureters have heretofore been devised for carrying out this end, butthe object. of the present invention is to provide a device of thisclass which may be constructed easily and inexpensively and the sainetime result in an extremely eiiicient means for producing' the desiredresult.

lilith the foregoing general object in view,

the invention resides in the novel features of construction and uniquecombinations of.

parts to be hereinafter fully described and claimed, the descriptivematter being supplemented by the accompanying' drawings which iorni apart of this specification and in which:

Figure l is a vertical section ci the iinproved carburetei';

Fiets.4 2, 3 and l are horizontal sections on the planes of the lines22, 8 3 and 4 4, respectively, of Figc. 1, looking in the directionsindicated by the arrows;

Fig. 5 is a vertical transverse section on the plane indicated by theline 5-5 of Fig. l; and a y Fig. 6 is a detail longitudinal sectionlsiini- 'lar to the upper portion of Fig. l, but illus trating a modifiedform of construction.

in the drawings above briefly described, the numerals i and l designaterespectively a fuel reservoir and a Water reservoir, the

two lbeing preferably, though .not necessarily, cast integrally as shownclearly in Fig. l. The inlets of the reservoirsl and 1 are provided Withany appropriate type of constant level device such as the floatycontrolled valves 2 and 2', and in order that either gasolene orkerosene may be fed to the reservoir l, as occasion may demand, a pairof supply tubes 3 and arc provided,

either one of which may be placed in coin-- inunicatiou with the maininlet tube by means oi: a three-way valve 6. in inost in stances,frasolene Will be used as `the fue? in starting, and until the enginehas been heat ed to such a degree as to allow kerosene to be readilyemployed.` When this degree of heat is obtained, however, the valve 6 isAoperated so` that kerosene, or any other rather heavy; oil, may besupplied to the chamber l.

Air passages .'Z and 7 lead vertically .through the tvvo reservoirs land 1 respec tively, suitable nozzles 8 and -8 'being pon sitioned insaid. passagesor supplying a spray of liquid thereto'as suction iscreated through said passages by the action oi: the engine, it beingobvious that since said noz .zles communicate respectively with thereservoirs l and l', they will supply the passage 7 with fuel, whereasthe passage will be furnished with a spray of Water. The upper ends ofthe passages 7 and 7 de liver into a pair oitubular perforated outletmembers 9 and 9 which rest upon a horizontal plate 10 which is securedover and closes the upper ends of the reservoirs, the member 9 being1preierably of less size than the member 9 since less Water than fuel isto be handled by the device. i peripheral wall iiieinber 1l rests on thplate 10 and is suitably secured thereto, said Wall ineinberhaving atransverse parti-tion l2 which divides the space circuniscribed by saidineinber, into a pair of heating cliain-.

pipe le extending` through both'chambers' 13 and 13 and having` means atits ends for connecting,l it to the usual or any pre erred type ofexhaust manifold, so that the hot gases passing through said pipe willAperforin the heating function effectively. Around the outlet members 9and 9, the pipe lli is provided with anv annular series oit preferablytf-shaped lieatradiating' Webs l5 between which and other oblique Webs15,", on the sides of the pipe 14, the fuel mixture and the mixture ofwater` vapor' and air must pass from said outlet members, beforetraveling to the upper ends of the chambers 13 and lffroin which themixtures formed dell* .are Withdrawn. `The upper side of the flat pipe14 will also in most cases 'be provided with heat radiating Webs 16which are preferably arranged as depicted in Fig. 2, al-

though any other suitable disposition couldv well be utilized. A. topplate 17 closes the upper ends of the chambers 13 and 13 and is rigidlysecured in place in any preferred manner, said plate ,having an outletopening 18 leading from thechainber 13, and similar opening 18 whichcoinmunieatesyw'ith the `ehainloer 1. A suitable dome 19 rests on I andis secured to the plate 17, Said dome ex-- 'tendintr over both openings18 und 18 ,andiV having a short vertical disehiu-ge pipe 20 whichregistere with the opening 18 as shown clearly in Fig. l, said pipebeing adapted for tering the outlet pipe 20, is whirled arounf to insurethorough mixing thereof with the vvolatile mixture rising through saidpipe from the chamber 13.

A highspeed air inlet 23 is provided iu the dome 19 for supplying an`auxiliary quantity of air to the passage Q0 when the engine runs fasterthan pre-determined speed.

allowed to mingle with the mixture in the,

rThe air from the inlet 23 may be dome ll), by the provision of aeonstruetion .stichs that illuutrated in Fig. (3. or a hori 'onta'lpartition 24 may he provided in ,said dome, So that the mixture will beconfined beneath thispartition, whereas the air conn ing into the intakewill flow between t`h`e partition and the top et' the dome, and willenter thopipe 20 through perforations spaced above the perforatious 22above de serileed. Either construction is highly eilieient and I merelyillustrate both to dis- -lose the two ways of obtaining required result.

The improved efnfbureter is installed hy emmer-ting its outlet pipe 20""'th the iu lake i'nanit'old Q1, and eonneeti its euh pipe 'ifi withthe exhaust manifold of the engine, as will beelear from Fig. l. EitherA,grasolene or oil 'will now he supplied to the reservoir l through thetuhes 3, t and 5. and the valve 6, and the constant level dei vite will.cui; oil' A'the supply at .the valve 2, when it has risen to therequired level in the nozzle` 8. Similarly, water is supplied to thereservoir l 'through the inlet pipe 5', and the autmnatie regulating'means oi the valve E2 culs oil the supplu when the water level has risento the reiuaired extent. En starting Ithe i'notov;4v oler-ie will inmost he tedv to the r: e5-voir to ineure easy a vipaaeae thehot pipe 14,so that this mixture is eonverted instantaneously into a mixture oli airand Steam, which passes into the deine lt* and then enters the pipe Q0through the perfqrations 2:2 provided for this iurposi. Since themixtures of air and i'uel and ail' and steam enter the pipe 20 atsubstantially; the saine point, an eii'eetive mixing takes place,particularly in View of the tangential arrangement of the perforation2:1. and a highly volatilized mixture is thus insured which will operatethe motor to irreal, ad. vantage.

Preferably used in connection with the features above described, is theusual ehehe valve 26 for the passage 7, and a siiwiia; valve 26 for thepasiage 7. lt may he necessary to use both of these ehoifes whenstarting, but in most cases it will only e necessarylto operate thevalve 26', in order that Water .may not vhe drawn into the intakemanifold and mixed with the gaeolene, since this would cause a low gradefuel he fore heating of 'the exhaust pipe.. Ar this heating takes place,however, the eh 26 may again he opened., together with tl 1 valve 26, ifthe latter has been eloeed, so that the fuel, Whether the latter hegasolene or oil, will be supplied with a quantity of steam and airmixture for producing the Well known results, :auch as increasing powerof the motor and minimizing ear-hen deposits.

From the foregoing, taken in connection with the accompanying drawings,it will oo 'one hat although the improved earhu l'df) ,veter is ofcomparatively simple and inert-- pensive eonstruetiom it `will hief ucient and durable. Sinee probably results; are obtained :from the rtalle shown and described, these 'features are Jy preference employed,but l wish it understood that Within the scope et 'the vention aselaimed,'numereus minor ehanges ,1

may well he made.
